nvgpu_err() macro with nvgpu_readl() call results in a
volatile access. This violates PRE31-C rule - "Using an unsafe
function-like macro with side effect in argument nvgpu_readl()"
due to side effect of a volatile access.
Fix this by moving nvgpu_readl() calls before nvgpu_err().

nvgpu_rc_pbdma_fault just checks for the id and id_type from struct
nvgpu_pbdma_status_info. These contain invalid values during chsw_load
and chsw_switch. This patch corrects the above bug by checking for the
chsw status and then loading the values for id and type.
The current code reads the pbdma_status info after clearing the
interrupt. Other interrupts can cause enough delay between clearing the
interrupt and pbdma switching the channel leading to invalid channel/tsg
ID. Correct that by reading the pbdma_status info register before
clearing of the pbdma interrupt to correctly read the context
information before the pbdma can switch out the context.

MISRA Advisory Rule 10.5 states that the value of an expression should
not be cast to an inappropriate essential type.
This change removes five violations of this rule that involve casting
boolean results to unsigned values:
* pass 1/0 (instead of true/false) to nvgpu_atomic operations
* fix skip_mask handling in gm20b_gr_init_pd_skip_table_gpc()
* fix l3_alloc flags check in nvgpu_gmmu_map_locked()
This change also eliminates several MISRA Advisory Rule 4.6 violations.
