Subject: RDMA/bnxt_re: Use bitmap_zalloc() when applicable
Patch-mainline: v5.17-rc1
Git-commit: 81ff48ddda0b7e1d4d1251d2a9c8e4059cd9456f
References: jsc#PED-1494
Use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid
some open-coded arithmetic in allocator arguments.
Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.
