msm:ipa: Address the -Wmisleading-indentation warning

There is braces missing for the if condition and leads to warning
of drivers/platform/msm/ipa/ipa_v3/ipa.c:3337:3: warning: misleading
indentation; statement is not part of the previous
'if' [-Wmisleading-indentation]. Fixed warning with proper braces
for the if loop.
